A 182-page report issued September 1 by the United States National Research Council warns that the amount of debris in space is reaching “a tipping point”, and could cause damage to satellites or spacecraft. The report calls for regulations to reduce the amount of debris, and suggests that scientists increase research into methods to remove some of the debris from orbit, though it makes no recommendations about how to do so.

NASA sponsored the study.

A statement released along with the report warns that, according to some computer models, the debris “has reached a tipping point, with enough currently in orbit to continually collide and create even more debris, raising the risk of spacecraft failures”. According to the Satellite Industry Association, there are now about 1,000 working satellites in Earth orbit, and industry revenues last year were US$168 billion (£104.33 billion,€119.01 billion).

The debris consists of various objects, such as decommissioned satellites and exhausted boosters, but the vast majority of the particles are less than one centimetre across. 16,094 pieces of debris were being tracked as of July, although estimates put the current number at over 22,000. The total number of fragments is thought to be as high as tens of millions. While most of the debris is very small, some of it is travelling at speeds as high as 17,500 mi h^-1 (28,164 km h^-1; 7,823.3 m s^-1).

The International Space Station sometimes has to dodge larger fragments, and in June its crew was forced to prepare to evacuate due to a close encounter with debris.

The UK Space Agency told Wikinews that space flight “is likely to be made more difficult” by the debris. However, communications will “[n]ot directly” be affected, “but if the GEO ring became unusable, there is no other altitude at which objects appear [‘]geo-stationary[‘] and so all antennas on the ground would then have to move in order to track the motion of the satellites”.

Donald J. Kessler, the lead researcher and former head of NASA’s Orbital Debris Program Office, said that “[t]he current space environment is growing increasingly hazardous to spacecraft and astronauts,” and suggested that “NASA needs to determine the best path forward for tackling the multifaceted problems caused by meteoroids and orbital debris that put human and robotic space operations at risk.”

Two events are thought to be the largest individual sources of space debris. Kessler said that “[t]hose two single events doubled the amount of fragments in Earth orbit and completely wiped out what we had done in the last 25 years”.

The first of these was a controversial 2007 Chinese anti-satellite weapon test, which smashed the decommissioned weather satellite Fengyun-1C into approximately 150,000 fragments over a centimetre in size—making up roughly twenty percent of all tracked objects—537 miles above the Earth’s surface.

The Chinese government has so far failed to respond to Wikinews’s queries regarding the incident.

The other is a 2009 collision between twelve-year-old active satellite Iridium 33 and the defunct Russian Strela-2M satellite Kosmos-2251—both weighing in excess of 1,000 lbs (454 kg)—that occurred 490 miles over Siberia, the first such collision. The Iridium satellite was replaced within 22 days, according to Iridium Communications, who operated it.

In a statement released to Wikinews, Iridium Communications said that they “received no warning of the impending collision. Although commercial projections of close encounters (commonly called conjunctions) were available, the accuracy of those projections was not sufficient to allow collision avoidance action to be taken.” They also made the assurance that the Air Force Space Command and United States Strategic Command now provide them with information through the Joint Space Operations Center, and that “when necessary, [they] maneuver [their] satellites based on this information to avoid potential collisions. [They] believe this is a substantial first step in better information sharing between the government and industry and support even more robust interaction which can provide better and more efficient constellation operation.”

Iridium expressed their support for “[l]ong-term investment to improve Space Situational Awareness” and “[i]mproved information sharing between industry and the U.S. government”, as well as more “[g]overnment support for policy and processes which would permit sharing of high-accuracy data as required to allow reliable assessment and warning” and “[i]ncreased cooperation between the government and U.S. and foreign commercial operators.”

They maintained that “the Iridium constellation is uniquely designed to withstand such an event. Because of the resilient and distributed nature of the Iridium constellation, the effects of the loss of a single satellite were relatively minor”, and that “any other system, commercial or military, which experienced the loss of a satellite, would have suffered significant operational degradation for a period of months if not years.” Nonetheless, the company is “concerned over the increasing level of risk to operations resulting from the debris in space.”

The report makes more than thirty findings, and more than twenty recommendations to NASA. None of the recommendations regard how to clean up the debris. However, it does cite a report by the Defense Advanced Research Projects Agency (DARPA), which suggested various possible techniques for catching and removing space debris, such as magnetic nets.

However, international law does not allow one country to collect another’s debris. George J. Gleghorn, vice chair of the committee, observed that “[t]he Cold War is over, but the acute sensitivity regarding satellite technology remains”.

The debris will, in time, be pulled into the earth’s atmosphere—where it will burn up—by gravity, but more debris is being created faster than this can happen.

The report recommends collaborating with the United States Department of State on “economic, technological, political, and legal considerations.” As already mentioned, international law does not allow one country to collect another’s debris.

According to the report, “[t]he problem of space debris is similar to a host of other environmental problems and public concerns characterized by possibly significant differences between the short- and long-run damage accruing to society … Each has small short-run effects but, if left unaddressed, will have much larger impacts on society in the future.”

A spokesperson for the UK Space Agency told Wikinews that the organisation “does not have any plans to get directly involved with [the clean-up] initiative but through its involvement with NASA in the Inter-Agency Space Debris Coordination Committee, it is conducting studies to identify which objects present the biggest hazard and how many objects may need to be removed and from where.” It says that the viability of such an operation is “a question of treating the symptom or the cause of the problem. Building more physical protection is costly and if the environment deteriorates too far, becomes unviable. It is best to treat the root cause, the presence of debris in orbit, and remove the large objects before they can break up into many thousands of uncontrolled fragments capable of destroying a satellite on impact.”

The spokesperson also pointed out that “[u]nder current licensing regimes (such as in the UK), countries are now obliging operators to remove satellites from crowded regions of space at the end of operational life”.

Wikinews extended invitations by e-mail on March 23 to multiple candidates running in the Texas’ 6th congressional district special election of May 1 to fill a vacancy left upon the death of Republican congressman Ron Wright. Of them, independent candidate Adrian Mizher agreed to answer some questions by phone on March 30 about their campaigns and policies. The following is the interview with Mr Mizher.

Mizher describes himself as a senior loan closer on his LinkedIn profile at BBVA USA, a Birmingham-based subsidiary of Banco Bilbao Vizcaya Argentaria. He has lived in Kennedale, Texas for five years and the Dallas-Fort Worth metropolitan area for 16 of the last 24 years. A cum laude graduate of Southwestern Adventist University, he grew up in Philadelphia, Pennsylvania and has lived for eight years in Albuquerque, New Mexico. He endeavours to bring “a never ending fight for fidelity to the Constitution and promotion of our Conservative values”, speaking to Wikinews on matters ranging from the economy to immigration.

An Inside Elections poll published on March 18 shows Republican candidate Susan Wright, the widow of Ron Wright, is ahead by 21% followed by Democrat Jana Sanchez with 17% and Republican Jake Ellzey with 8% with a 4.6% margin of error among 450 likely voters. The district is considered “lean Republican” by Inside Elections and voted 51% in favour of Donald Trump in last year’s US presidential election. This is down from 54% for Trump in 2016’s presidential election, the same poll stated.

Gay Talese wants to go to Iraq. “It so happens there is someone that’s working on such a thing right now for me,” the 75-year-old legendary journalist and author told David Shankbone. “Even if I was on Al-Jazeera with a gun to my head, I wouldn’t be pleading with those bastards! I’d say, ‘Go ahead. Make my day.'”

Few reporters will ever reach the stature of Talese. His 1966 profile of Frank Sinatra, Frank Sinatra Has a Cold, was not only cited by The Economist as the greatest profile of Sinatra ever written, but is considered the greatest of any celebrity profile ever written. In the 70th anniversary issue of Esquire in October 2003, the editors declared the piece the “Best Story Esquire Ever Published.”

Talese helped create and define a new style of literary reporting called New Journalism. Talese himself told National Public Radio he rejects this label (“The term new journalism became very fashionable on college campuses in the 1970s and some of its practitioners tended to be a little loose with the facts. And that’s where I wanted to part company.”)

He is not bothered by the Bancrofts selling The Wall Street Journal—”It’s not like we should lament the passing of some noble dynasty!”—to Rupert Murdoch, but he is bothered by how the press supported and sold the Iraq War to the American people. “The press in Washington got us into this war as much as the people that are controlling it,” said Talese. “They took information that was second-hand information, and they went along with it.” He wants to see the Washington press corp disbanded and sent around the country to get back in touch with the people it covers; that the press should not be so focused on–and in bed with–the federal government.

Augusten Burroughs once said that writers are experience junkies, and Talese fits the bill. Talese–who has been married to Nan Talese (she edited James Frey‘s Million Little Piece) for fifty years–can be found at baseball games in Cuba or the gay bars of Beijing, wanting to see humanity in all its experience.

Below is Wikinews reporter David Shankbone’s interview with Gay Talese.

At 11:45am on January 16, in Vladivostok, Russia, a fire broke out on the three upper floors of the Sberbank building.

Photographs taken by eye-witnesses show people, who were trapped, dropping from 8th floor windows to their deaths. According to some reports the firemen who were dispatched to the scene were pre-occupied at the rear of the building. They had apparently been ordered to evacuate the bank and its management from the area, which was not under immediate threat.

Official Russian media initially denied the fire, accusing the reports of being false.

Russian media later confirmed 7 and then, 9 dead. Witnesses and those rescued from the burning building have claimed that the figure exceeds 50.

A maintenance employee who worked in the building was quoted as saying, “I know at least about 13 dead inside … that’s the least I’ve noticed, not to consider those who’ve dropped down … 8 of them dropped, looking at the three already dead on the ground, but they went through the windows without hope to be rescued … They collected and hid the dead bodies inside. I work at this building! I know its layout very well! To declare, as it become clear, a less number of the dead later.”

“My daughter worked in a justice department,” – Natalia, one of the witnesses said. “She said that there were actually much more dead – up to 70. She went on the dead bodies, getting out from the building … some of them were so scorched, that it was impossible to identify them… 9 victims? That’s a lie!”

Georic, a witness: “The cops (“menty”), whom I know, say that they’ve been loading the dead bodies all night long.”

Lelya has posted her evidence on January 21, 2006 on the web-site http://news.vl.ru/vlad/2006/01/18/tradegy/ “My brother worked in that building, on the 6th flour. So, the night after the fire they visited the building to collect the documents, etc. and they saw how workers transported the dead bodies. He said, there were 50-60..”

The United States House of Representatives has passed The Affordable Health Care for America Act or HR 3962, a bill which would ensure that 95–96% of US citizens receive affordable health care.

HR 3962 was passed with 220 yeas and 215 nays. Democrats in the house needed at least 218 votes to pass the bill. 39 Democrats voted against the bill, which contained the Stupak amendment. This amendment curtailed women’s abortion rights. One Republican, Representative Joseph Cao of Louisiana, voted for the bill.

The US Senate has drafted their own health care bill, S. 1679. It is not yet known when the Senate will vote on their version of the bill, but in the end both versions must be merged into one with both the House and Senate voting again.

The health care program associated with HR 3962 is estimated to cost over US$1 trillion over ten years, according to the Speaker of the House Nancy Pelosi, who states that it will result in “[…] not one dime added to the deficit.”

US President Barack Obama says that he is “confident” that the Senate will be able to come to an agreement and pass a completed bill. Obama added that he hopes to sign a “comprehensive health insurance reform into law by the end of the year.”
